4 years ago The same comment for portfolio performance graphs: The DB has stock history but once a stock is sold it is currently expected to be deleted from the tables leaving no ability to calculate previous value for performance trend. we can make a small portfolio performance table holding table id, date, and value at that date?
As a user I should be able to see my theoretical gains/losses from all or one of my portfolios, based on the price when I added a stock to my portfolio and current prices. This gives me the added convenience of not having to calculate this myself - saving time and allowing me to focus on profits in other ways.
